Help Please :)
f(x) = 5x +7
and
g(x) = -2x - 4

f(g(x)) = -2x + ????

Answers

Answer 1

Answer:

f(g(x)) =  - 10x - 13

Step-by-step explanation:

Given functions:

f(x) = 5x +7

and

g(x) = -2x - 4

Work out the composite f(g(x)):

f(g(x)) = f( -2x - 4) = 5( - 2x - 4) + 7 = -10x - 20 + 7 = - 10x - 13
Answer 2

Answer:

f(g(x)) = -10x - 13

???? = - 8x - 13

Step-by-step explanation:

f(x) = 5x +7

and

g(x) = -2x - 4

f(g(x)) = f(-2x - 4) = 5(-2x - 4) + 7

f(g(x)) = -10x - 20 + 7

f(g(x)) = -10x - 13

f(g(x)) = -2x - 8x - 13

A pharmacy claims that the average medication costs $32, but it could differ by as much as $8. Write an absolute value inequality to determine the range of medication costs at this pharmacy.

a
|x − 32| ≥ 8

b
|x − 8| ≥ 32

c
|x − 32| ≤ 8

d
|x − 8| ≤ 32

Answers

Step-by-step explanation:

So,

We can tell that the most expensive medication costs $40 and the cheapest costs $24.  Thus, only options A and C are left.

To see which inequality is true, test a value, such as $30, in the equation in option C.

|30 - 32| ≤ 8

|-2| ≤ 8

2 ≤ 8

Option C is correct.

–14d + 16 = –6d + 6 + 18

d =

Answers

Answer:

–14d + 16 = –6d + 6 + 18

d = -1

Step-by-step explanation:

I used a calculator, pls let me know if im incorrect

Answer:

d = -1

Step-by-step explanation:

combine like terms

add the coefficients(numbers with variables) together and add the integers together.

-14 d + 16 = -6d + 6 + 18 ------ add 6d on both sides

-8d + 16 = 6 + 18 ---- subtract 16 on both sides

-8d = 18 - 16 + 6

-8d = 2 + 6

-8d = 8 --- divide -8 on both sides

d = -1

Hello could someone solve this please? The answer is: x = -1 or x = -2/25.
I would like a step by step solution please

Answers

Answer: the answer only -2/25

Step-by-step explanation:

[tex](5x + 3)^{2}= (\sqrt{3x+7} )^{2}[/tex]

[tex]25x^{2} +30x++9 = 3x+7[/tex]

[tex]25x^{2}+27x+2=0[/tex]

What is the x-intercept of the line with this equation?

−5x + [tex]\frac{1}{5}[/tex]y = 15

Answers

The x-intercept is the point on the graph where it crosses the x-axis. It’s also the value of the x-coordinate when y = 0.

To find the x-intercept, set y = 0:

-5x + 1/5(0) = 15

-5x + 0 = 15
-5x = 15

Divide both sides by -5:

x = -3.

Therefore, the x-intercept is (-3, 0).

so...

to find out what x is we need to divide 6 by 2

which is

so we know that x-3 has to be equal to 3

therefore x=6

and to check:

6-3= 3

so

What the answer of this question?

Answers

Answer:

w = 3 cm

Step-by-step explanation:

The area (A) of the triangle is calculated as

A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the height )

Here b = 5 and h = 6 , then

A = [tex]\frac{1}{2}[/tex] × 5 × 6 = [tex]\frac{1}{2}[/tex] × 30 = 15 cm²

Now the area of the rectangle is 15 cm²

area = length × width , that is

5w = 15 ( divide both sides by 5 )

w = 3 cm

Answer:

2.5

Step-by-step explanation:

equation the two areas in an equation and they are equal

[tex] \frac{1}{2} base \times height = length \times \: width[/tex]

but the width is w

substituting the values,

[tex] \frac{1}{2} (6)(5) = 6 \times w \\ 15 = 6w \\ w = \frac{15}{6 =} = \frac{5}{2 } = 2.5[/tex]
